There's an air compressor mounted to the engine. That compressor charges one (or several) tanks. Air from the primary system is fed continuously to the emergency chamber of the spring brake chambers - this provides hold off pressure to release the spring brakes. When the treadle valve (brake pedal valve) is depressed, air from the primary air system (and usually the secondary air system for the front axle) is routed to the service chamber of the brake chambers, and this usually rotates and S cam to push the brake shoes out into the brake drum (although specifics at this point will differ with disc brakes and piston brakes).

What do air brakes use to make the brakes work?
Compressed air.
Is it true that An air brake system uses compressed air to apply the brakes?
Yes
Do air brakes use brake fluid?
No, they use air pressure or actually the lack of air pressure to stop the vehicle. The brakes are fully on until pressure builds up in the tank releasing the brakes. When you push the brake pedal this removes air from the system and applies the brakes.
Why not use compressed air in car brakes?
The advantages in using them in large commercial vehicles aren't necessarily present in small passenger cars.
What systems use pneumatic systems?
One of the most common is the bus or heavy goods vehicle - fitted with air brakes. Similarly the brakes on trains. However there is a huge range of industrial tools, machines and control systems powered by compressed-air.

What is the study of compressed air?
compressed air science
Which categories is usage of compressed air and gas divided into?
The three major categories of usage for compressed air and gas are: compressed air and gas for process services, compressed air for power, and compressed air for general industrial applications.
How do hgv brakes work?
My understanding is this: HGV brakes operate on compressed air as I am sure you know, however the brakes are spring loaded which means rather than applying the brakes, the air pressure is what keeps them OFF, so when the system runs out of air the brakes will lock on solid. when you are driving and you push the brake pedal what is happening is that the pedal valve is shutting off the supply of air to the brake chambers and the friction material (either shoes or pads) is drawn by spring pressure towards the disc or drum.
What is the purpose of a compressed air dryer?
A compressed air dryer is used to remove water vapor from compressed air. Compressed air dryers are used mostly in commercial and industrial facilities.
What do compressed air dryers do?
A compressed air dryer is a device for removing water vapor from compressed air. Compressed air dryers are commonly found in a wide range of industrial and commercial facilities.
How does pneumatic air gun work?
it works with compressed air
